The present application relates to the technical field of medicine, and discloses application of gastrodin in preparation of medicine for preventing and treating radioactive liver injury, wherein the radioactive liver injury is liver injury caused by ionizing radiation exposure. It is found that the gastrodin can effectively intervene in specific mechanism of the radioactive liver injury, significantly reduce the mortality of the radioactive liver injury mice, reverse the hepatic veno-occlusive disease and the core pathological features of liver fibrosis of the radioactive liver injury, and more specifically treat the radioactive liver injury. On the other hand, the gastrodin can be used before radiation exposure to prevent serious radioactive liver injury after radiation exposure.

This application provides an automated liver segmentation modeling method and system based on a hybrid neural network, relating to the field of medical imaging technology. The method includes: preprocessing acquired raw liver images to obtain a three-dimensional liver image; wherein the three-dimensional liver image includes liver parenchyma, portal vein, and hepatic vein; inputting the three-dimensional liver image into a trained segmentation model to obtain liver parenchyma masks, portal vein masks, and hepatic vein masks; dividing the liver parenchyma into multiple watershed partitions based on the liver parenchyma masks, portal vein masks, and hepatic vein masks; determining the standard liver segment corresponding to each watershed partition based on preset liver segmentation rules; and elastically deforming the watershed partitions based on the standard liver segments corresponding to the watershed partitions to obtain deformed watershed partitions. This application can reflect the individualized vascular variation characteristics of patients.
